Title: Method for locally modifying electronic and optoelectronic properties of crystalline materials and devices made from such materials
Inventor: HOMEWOOD KEVIN PETER
IPC: H01L33/02
Filed: 2001-06-07
Granted: 2013-02-26
Abstract: An electronic or optoelectronic device fabricated from a crystalline material in which a parameter of a bandgap characteristic of said crystalline material has been modified locally by introducing distortions on an atomic scale in the lattice structure of said crystalline material and the electronic and/or optoelectronic parameters of said device are dependent on the modification of said bandgap is exemplified by a radiation emissive optoelectronic semiconductor device which comprises a junction (10) formed from a p-type layer (11) and an n-type layer (12), both formed from indirect bandgap semiconductor material. The p-type layer (11) contains an array of dislocation loops which create a strain field to confine spatially and promote radiative recombination of the charge carriers.

Inventor: KOTESKY GARY L
IPC: B01D39/12
Filed: 2002-11-26
Granted: 2010-10-12
Abstract: A filter for use in a waste water discharge system including a first channel defining a receptacle for a filter and a second channel connected generally orthogonally to the first channel providing an outlet from the filter receptacle. The filter has an axial support of a pre-selected length, a plurality of bristles fixed to the axial support extending radially outward to define an outer margin. The outer margin of the bristles, at some portions along the pre-selected length, are at least equal to an inside dimension of the channel defining the receptacle. A handle is fixed to the axial support facilitating the placement and withdrawal of the filter element in the filter receptacle. A shield member is provided that is generally conformable to the inside surface of the filter receptacle. The shield member has a length dimension sufficient to cover the outlet leading to the second channel for blocking any flow of waste water into the second channel during replacement of the filter element.

Abstract: A structural band saw blade (10, 110) is defined by a plurality of teeth (12, 112) spaced relative to each other with variable height and set, and a back edge (46, 146) located on the opposite side of the blade relative to the cutting edge. Each tooth of the band saw blade defines a tip (40, 140), a rake face (42, 142) formed on one side of the tip, a primary clearance surface (44, 144) formed on the opposite side of the tip relative to the rake face, a secondary clearance surface (48, 148) adjacent to the primary surface, and a tertiary clearance surface (50, 150) adjacent to the secondary surface. The primary, secondary, and tertiary surfaces respectively define first, second and third acute relief angles (A, B, C) wherein the second angle is less than the first angle and the third angle is greater than both angles. A rake face protrusion (54, 154) is formed opposite the rake face relative to the tip and extends over one end of a weld zone (52, 152) and projects outwardly relative to a plane of the rake face. One or both the secondary and tertiary surfaces projects outwardly from the rake face plane opposite the protrusion to form an increased tooth thickness at the weld zone and prevent tooth strippage.

Granted: 2010-07-20
Abstract: A system of interconnecting structural components for supporting and forming suspended concrete stabs that allow removal of form panels without disturbing the slab support posts (shores). Additional features of the system accommodate changes in suspended slab thickness, horizontal slab dimensions that are not multiples of the basic component dimensions, slab edge cantilevered form panels, attachment to walls and remote manipulation of form panels from the floor below using an erection staff. The primary system components are panels, support posts, telescopic beams, adjustable hanger connections, wall hangers, wall beams, raking shore assemblies and erection/stripping staffs. Form panels are directly supported by the shores without the use of an intermediate member (usually a beam) that is common practice in the concrete forming industry. The system reduces the number of required components that in turn reduces the capital cost to the user and improves his labor efficiency and quality of the concrete surface.

Title: Holding device for a ceramic blank
Inventor: FILSER FRANK
IPC: A61C5/77
Filed: 2001-12-03
Granted: 2010-05-18
Abstract: A holding device (42) comprises a cylindrical or prismatic, porous ceramic blank (10) and means for clamping in a machine tool for processing the blank (10) by removing material, in order to produce a ceramic workpiece (18). A narrow frame (12) is fixed by an adhesive connection over at least part of the periphery of the blank (10), which is held without stresses, in the area of a plane encompassing the longitudinal middle axis (A) of the blank. Said frame (12) only covers a small part of the surface of the blank (10) and can be detached and held in a stable holder (24) with a clamping adapter (34), in such a way that it cannot slide. The entire combination is fixed in the machine tool in such a way as to be resistant to twisting and sliding. The ceramic workpiece (18) emerges continuously from the ceramic blank (10) without predetermination of the advance direction, until holding segments (20) which can then only be freely selected according to number and location have been formed. Said holding segments (20) end on the residual material of the blank in the area of the frame (12) or on the frame (12) itself. The holding device is used especially as a workpiece (18) for producing fully ceramic dental prostheses, particularly crowns or bridges.
